新型膨胀型阻燃剂-硼酸锌复合体系对聚苯乙烯阻燃性能的影响
Effect of Novel Intumescent Flame Retardant-Zinc Borate System on Flame Retardancy of Polystyrene
摘要
Abstract
To enhance the flame retardancy of polystyrene(PS),reducing its heat and smoke release during combustion,a novel flame retardant(MAP)was prepared via electrostatic self-assembly,and the new intumescent flame retardant(N-IFR)composed of MAP-polyphosphoric ammonium(APP)-pentaerythritol(PER)was compounded with zinc borate(ZB)and added to PS.The results showed that the limiting oxygen index of PS-22%N-IFR/1%ZB composites increased to 28.3%,achieving UL-94 V-0 rating in vertical burning tests.Compared to pure PS,the peak heat release rate,total heat release,and total smoke production decreased by 67.6%,11.8%and 25.9%,respectively.The synergistic flame retardant effect of ZB and N-IFR promoted the formation of a high-quality char layer and effectively suppressed the heat and smoke release of the PS.关键词
